侵彻子弹在机场跑道中的爆破实验研究

Experimental Study on the Penetrator Explosion in Runway

为研究侵彻子弹对机场跑道的毁伤效果,进行了侵彻子弹在各级机场跑道中的爆炸实验。实验结果表明,侵彻子弹在各级实验靶中最佳炸深时的破坏效果由大到小依次为沥青靶、二级靶、一级靶、特级靶;根据实验结果拟合得到炸深与爆坑半径的关系曲线,拟合曲线呈抛物线状,并得到可用于工程计算的公式;此外,拟合出单位炸深时爆坑半径与装药量的关系曲线。研究结果为侵彻子弹的引信设计提供了依据。

In order to study the damage effect of the penetrator explosion in runway, the experiments of penetrator explosion in all types of runway were developed. Results showed that the destructive degree from higher to lower at the optimal explosive depth of penetrator in all types of runway were bitumen target, target Ⅰ, target Ⅱ ,and super target respectively. The fitted curves of the relation between explosive depth and crater＇s radius were obtained, and the curve is a parabola, so the equation applied to the engineering computation was also acquired. Meanwhile, the curve of relation between crater＇s radius and mass of charge with one meter explosive depth was fitted. The study provided the foundation for the penetrator＇s fuse design.
